I am a researcher on the edge of Natural Language Processing (NLP) and Information Retrieval (IR). My current research focus is on text mining and retrieval in complex domains.
Since 2017, I have been employed as an Assistant Professor at the Leiden Institute of Advanced Computer Science (LIACS). I am affiliated with the Data Science Research Programme of Leiden University. I am group leader of Text Mining and Retrieval Leiden.
I currently supervise projects that develop and evaluate text mining and retrieval methods in a diversity of domains. My group works with a large diversity of textual data: grey literature reports, scientific and legal publications, EU law texts, health records, user-generated content in online patient communities (discussion forums), and news posts on social media.
I collaborate with many different public and private partners such as Sanoma, YoungCapital, the Ministry of Foreign Affairs, The Dutch National Institute for Public Health and the Environment (RIVM), Hogeschool Codarts, and KankerNL.
